It's normal that the Radio with android OS is a lil Bit Slow, because the limitation internal RAM and the operation speed is also influenced by the installation third party apps.
For the subwoofer channel,there is not a separate subwoofer channel setting, this unit can only support to output the lower audio frequency from 20~100Hz, which the special CD has.
Actually you can set the EQ mode to Jazz or rock to get the bass effect.
